Specifications include, but are not limited to: Review of data listed in the References section of this report, including pertinent background data, stereoscopic aerial photographs, in-house geotechnical data, published geologic maps, and soils data. Coordination and mobilization for subsurface exploration. Markout of existing utilities was conducted through Underground Service Alert (USA). Drilling, logging, and sampling of 11 borings to depths ranging from approximately 20 to 25 feet. The purposes of the exploratory borings were to evaluate the subsurface soil conditions along the subject alignment and to obtain soil samples for laboratory testing. Performance of laboratory tests on selected soil samples obtained from the exploratory excavations to evaluate the in-place moisture content and dry density, gradation, plasticity, expansivity, R-value, sodium content, sulfate content, sodium sulfate content, and solubility potential (total salts). Compilation and analysis of the accumulated data.
